P0911 Foreign Currency Transactions

In JDE E1 9.2, we create JE s in foreign currency. Company currency is USD and JE created in SGD. There were 38 lines with various accounts. We notice there are lines which work out to be 5214.124472 for AA amount which has been rounded up to 5214.13 while expectation was it should be 5214.12 only. Similarly, there is an AA amount as 16.32683249 which should have been rounded up as 16.33 but system processed the amount as 16.32 only.

These kind of transaction over a period of time is causing issue in few of the accounts. Is there any document on how the calculation of Foreign Currency amounts happen for P0911 Application. Is there any set up where the rounding off amounts can be routed to any separate account.
